at temperatrro between 146@ and 170C F. (tfuriperatures of pasteurization) retotore as representing the highest most scientific state of the art of 'prel ino paring :toed for infants, inralids and oldi persons from cereals and milk and cream as practised by physicians skilled in dietetics,'it has been the practice to prepare a I gruel by boiling` in Watelwliole, cracked or rolled cereals three to six hours, or cereal I fleurs for fifteen minutes or longer, then to r cool the gruel until-it can be borne in the mouth, then to add the diastatic enzym to produce dextrin and maltose, and the de sired proportion oi milk and sugar, and then to heat this mixture to 150 to 41700 l?. for iiftecn to thirty minutes 'to pasteurize. Ilfhus such preparation of toed involves the above mei -ioned separate processes requiring skill and the use of a thermometer and the knowledge of how properly to use the thermometer for purposes of pasteurization. its pasteurization is accomplished between o-.i700 li., as thorough cooking of propinuted or milled cereals is possible 50041.00 as dextrin and maltose are st prepared from grueis at temperatures O-i'/O? by the action of diastatic' eneyins, a change in the curding property of cows mill? occurs at M-i700 that is, this temperature in addition to killing the bast ria in coude milk alters its properso rit -when it cones into contact with th are juices oii the human stomach it iialry curd, and as a suddenly apchang'e oil tlocculency of the mii;- ommiouted cereal, Water, inilk and enzyme takes let-eat about 1700 (te l i ture oit pasteruiisation) due to the coniminuted cereals and the diastatic enzynis in the mixture and indicates that ntuie is cooked and also pasteuriaed,

The process of preparing the food would be the same no matter what the source of the fat, protein and carbohydrates was.

ln a case Where inillr of any kind or in any forni is not tolerated a feeding mixture ofthe same percentage composition oi protein, fat and carbohydrates can be prepared by my process by using instead oi' milk or cream the quantities of Water, comniinuted cereals and diastatic enzyms, and fat, pro tein'and carbohydrates derived from other sources than milk. needed to impart to. the mixture the desired composition.

in case it is desired to omit or reduce the quantity of fat, 1oroteiu or carbohydrate in a feeding mixture the material which 'Would have furnished the objectionable element would be lett out or reduced in quantity.
